Crispy baked flounder is the perfect weeknight meal! Serve it with a fresh salad and your favorite sides for a simple, well-balanced dinner. It’s a delicious way to change up your dinner routine, and it’s packed with heart-healthy fats.

The flounder fillets are brushed with a honey mustard glaze, then topped with a crumb mixture made of crushed walnuts, pistachios and breadcrumbs. They get baked and broiled for the ultimate crisp, and truly just melt in your mouth.

How to make walnut & pistachio crusted flounder

Here’s what you’ll need for this simple recipe:

  • flounder fillets- this recipe would also be delicious with sole, or even salmon!
  • seasoned breadcrumbs
  • walnuts & pistachios- I like to crush them in a bag using the bottom of a jar, but you can lightly pulse them in a food processor to chop them up
  • dijon mustard
  • honey- I love using a spicy honey for an extra kick
  • fresh parsley
  • salt, pepper & garlic powder

The fish comes out crisp and flakey, and is a delicious way to eat more seafood during the week. I can’t wait for you guys to try it- I know you’re going to love it!

  1. This looks amazing.
    We avoid bread (my daughter is gluten free), would this recipe be highly compromised without the bread crumbs?

    • I personally love the added texture the crumbs bring, but it can be made without them. You can also use any GF breadcrumbs you like, or blend store brought grain free crackers into crumbs- I love the sea salt almond flour ones by Simple Mills!

  2. So good! Made this with wild caught salmon. Will keep this in our regular rotation! So good.
